[JUX-794] Mischievous teacher Kang Seulgi, after school gangbang! Lots of cream pies!

(Kang Seulgi X Male Students feat. TripleS Kotone)

The first snow of December falls steadily outside the frosted windows, quieting the world in a blanket of white. The heater hums faintly in the corner, but it’s losing its battle against the cold. Students shuffle into the room slowly, hands buried in their jacket pockets, faces flushed from the biting air. The class feels sleepy and subdued. Except for the back row.

Kang Seulgi enters with her usual composure, the click of her brown heels sharp against the silence. She sets a neat stack of books on the desk, brushing a strand of her orange hair behind her ear before peeling off her coat. Beneath it, she’s dressed with deliberate precision: a silky brown blouse that clings just enough and tight brown leather shorts that cut high on her smooth, bare thighs.

The contrast is striking. Warm layers on everyone else, while she stands there as though immune to the cold. Her round glasses frame her sharp gaze as she finally looks up.

“Good morning."

Seulgi says softly, her voice cutting through the muted hush.

“We’re continuing with evolution today. Open your books to page 54.”

The students comply, the sound of pages turning filling the room. But the boys in the back; Jaehyun, Minho, Jiho, Hyunwoo, and Seungmin; sit still and quiet, their jackets loose, ties undone. Their books remain closed, pens idle. They’ve made no effort to look interested, but Seulgi doesn’t acknowledge them.

She turns her back to the class and begins writing in large, fluid letters on the whiteboard: Natural Selection. Adaptation. Competition.

“In biology,"

She talks, evenly underlining the word Adaptation.

“natural selection determines who thrives and who doesn’t. It isn’t always the strongest who survive. It’s those who know how to adapt.”

Her voice is calm, almost melodic, but the rhythm of her movements is deliberate. She stretches slightly to underline a point, her blouse dipping faintly at the back. The motion feels natural, unremarkable to most. But she knows the back row is watching. She finishes writing and caps the marker with a snap.

“Now, let’s start with a quick recap.”

The minutes tick by slowly as Seulgi explains the core principles of evolution. The heater hums louder, groaning as though in complaint, but the room remains cold. Some students yawn quietly, their pens moving lazily over their notebooks.

Seulgi leans back against the edge of her desk, resting one hand beside her as she crosses her legs slowly at the knee. The motion is smooth, deliberate, and reveals the full length of her bare, toned thighs. The leather of her shorts catches the soft light filtering through the window, dark and sleek against her skin.

Her other hand adjusts the glasses on her nose as she continues.

“The environment decides which traits are an advantage. For instance, animals in cold climates adapt by growing thicker coats or conserving energy.”

A pause.

“In this case,"

She adds, her tone soft but edged.

“you could say survival is about knowing how to endure... or how to stand out.”

The words seem to settle heavily in the air. From the back, Jaehyun shifts faintly in his seat, dragging a boot noisily against the floor before stopping. Minho runs his fingers absently through his hair, though his gaze hasn’t moved from the front of the room. Hyunwoo’s pen is still, the cap flicked on and off in slow rhythm.

Seulgi knows what she's been doing to them for the last couple weeks. But she doesn't even grant the five of them a glance. She focuses instead on a stack of papers, as if oblivious to the tension.

Halfway through the lesson, Seulgi moves to the board again. She uncaps the marker, poised to add another word to her now pretty large collection of keywords: Selection.

The marker slips suddenly from her fingers, tumbling noisily to the floor.

“Oh."

She murmurs softly, pretending to be surprised.

Without hesitation, she bends at the waist to retrieve it. The movement is deliberate yet measured. Her blouse stretching faintly as she leans forward, the hem of her dark leather shorts lifting just enough to reveal the perfect shape of her bare thighs. For a second, just a second, there’s a faint glimpse of lace peeking above the line of her shorts. Black lace. That seems to hug her thighs perfectly underneath her shorts. The shape of her perfect ass makes the experience even more rewarding.

The silence that follows is deafening.

From the back, someone’s chair creaks faintly. Jaehyun sits perfectly still, his eyes fixed firmly on the edge of his desk. Minho stares straight ahead, though the faintest movement in his jaw betrays him. Jiho’s fingers pause mid-tap on his notebook, the rhythm forgotten.

Seulgi straightens slowly, marker in hand, and brushes a strand of hair over her shoulder. Her face remains perfectly neutral, as though nothing happened at all.

“Let’s continue."

She says smoothly, turning back to the board.

Toward the end of class, the lesson turns to competition as a key driver of natural selection.

“Competition isn’t always obvious."

Seulgi explains, sitting on the edge of her desk once again. This time, her posture is looser, more relaxed. One heel dangling lazily from her foot as her legs cross. The motion draws subtle attention to the clean line of her thighs, their smoothness standing out in stark contrast to the winter cold everyone else seems to be hiding from. She taps a finger lightly against the edge of the desk, as though in thought.

“Sometimes, survival depends on subtle advantages. A trait that sets one apart from the rest, even if no one notices it at first.”

She allows the words to hang for a moment, brushing her fingers idly along the hem of her blouse. She only barely moves her collar a little to the side. Just the slightest hint of her tits reveal the lack of a bra.

“Nature rewards the clever, the resilient, and those who can endure.”

From the back row, Jaehyun’s pencil rolls off his desk. He doesn’t pick it up right away. Hyunwoo exhales through his nose, sitting back with an expression carefully blank. Minho slouches lower in his chair, his arms crossed tightly over his chest as he looks out the window.

After an otherwise uneventful rest of the class, the shrill ring of the bell cuts through the stillness, breaking the calm atmosphere in an instant. Students jolt upright, snapping their books shut and packing up quickly. Seulgi uncrosses her legs slowly, sliding off the edge of her desk as she gathers her papers.

“Read pages 54 to 60 for homework. We’ll continue on Monday.”

The class empties slowly, students trudging toward the door. The back row lingers longer, as always. Jaehyun is the last to stand, slinging his bag over one shoulder and pausing just long enough to glance back at the desk. His expression gives nothing away.

When the door finally clicks shut, Seulgi exhales softly. She sets her papers neatly in a folder and picks up the red marker, turning it over in her fingers with a faint smile. They're close to breaking already.

The lunch bell echoes through the school, signaling a rare pocket of freedom for the students. The once-quiet halls turn chaotic as voices bounce off the walls, lockers slam shut, and footsteps patter quickly toward the cafeteria. The winter wind howls faintly outside, making the warmth of the building feel like a reluctant escape from the cold.

In the middle of it all, Seulgi walks with slow, deliberate steps.

Her outfit today is different from last week. Still professional but tailored to perfection. She wears a crisp, white blouse with the sleeves rolled neatly to her elbows. A slim black pinstripe vest hugs her torso, cinched with small silver buckles at her sides. Her short pleated skirt, just daring enough, grazes the tops of her bare thighs, leaving smooth skin visible with every stride. A loose black tie drapes over her blouse, and her tall black boots add a confident edge to the look. Her hair is sleek and straight today, cascading past her shoulders like liquid ink. The glasses perched on her nose frame her face, lending her the illusion of untouchable composure.

The sound of her boots clicks with every step as she makes her way toward the teacher's restroom, moving through the chaos with unbothered grace.

Near the far end of the hallway, the same five boys hang around the lockers like they own the place. Their jackets hang open over their uniforms, ties barely in place, looking perfectly disheveled in a way that only makes them stand out more.

As Seulgi rounds the corner, the sound of her heels cuts through the din of students moving past.

“Shit. There she is again."

Minho mutters under his breath, nudging Jaehyun with his elbow.

Jaehyun tilts his head back against the lockers, his lips twitching into a faint smirk as his eyes follow Seulgi.

“She’s been looking good lately.”

“Looking good?”

Jiho scoffs, his gaze shamelessly trailing up her legs. The short skirt shows off just enough to hint at her plump cheeks.

"That girl has cake.”

He feels Minho's elbow in his ribs a second later.

Hyunwoo snorts, biting back a laugh.

“No wonder she wears skirts like that. She knows what she’s doing.”

Seungmin shakes his head faintly, though his expression mirrors theirs.

“Teachers aren’t supposed to look like that, man.”

Jaehyun chuckles lowly, finally dragging his eyes away as Seulgi disappears down the hall.

“Doesn’t seem like she cares what’s ‘supposed to’ happen.”

Their laughter blends into the noise of the hallway, but Seulgi doesn’t acknowledge them. She doesn’t turn her head, doesn’t falter in her stride. She hears them though. She always hears them.

And maybe that’s part of why she does it.

The teacher's restroom is quiet, a stark contrast to the buzz of the hallway outside. The heavy door clicks shut behind her, sealing Seulgi into stillness. She exhales softly, setting her bag down on the sink as she steps toward the mirror.

The reflection staring back at her is calculated: the perfect balance between sharp professionalism and something far less innocent. The white blouse clings perfectly under the vest, the short skirt flaring just enough to draw attention to the smooth, bare skin of her thighs. Her tie hangs loosely over her chest, like a deliberate afterthought, while her straight hair frames her face in soft contrast to the sharpness of her outfit.

Seulgi’s fingers brush the hem of her skirt lightly, smoothing the fabric down as she studies herself.

“That girl has cake.”

The words echo faintly in her mind. She should be disgusted. She should be offended. But instead, her lips curve into the faintest, most secretive of smiles.

She doesn’t understand why she feels this way. Why the thrill of being noticed has started to creep under her skin like an addiction. It’s not the boys themselves. She knows what kind of attention they’re giving her. It’s rude, thoughtless, the kind of thing she would’ve shut down immediately if they said it to her face.

And yet...

Her fingers tighten faintly against the edge of the sink as she leans forward, letting her gaze drift over her reflection.

It’s the power she likes. The quiet control.

Outside, the world sees a perfect teacher. A young professional with sharp glasses and flawless composure. But here, now, with the door shut and the mirror reflecting every inch of her body, she can admit the truth: she enjoys the attention. She enjoys being seen.

What’s wrong with me?

She doesn’t have an answer.

When Seulgi leaves the bathroom, the hallway has quieted. Most students have already gathered in the cafeteria, leaving only a handful lingering by their lockers or walking toward the stairs.

The boys are gone, though their presence still feels like a shadow in the back of her mind. Seulgi adjusts her tie, brushing it against the edge of her blouse as she walks. The sound of her boots echoes faintly in the empty corridor.

She tells herself it doesn’t matter.

They’re just kids. Troublemakers.

But as she steps into the faculty lounge, greeted by the hum of conversation between colleagues, the secret thrill still lingers under her skin.

Let them look. Let them talk.

Her expression remains neutral, calm, untouchable.

No one would ever know.

The classroom hums with faint energy, though no one is talking. Outside, snow continues to fall in quiet sheets, blurring the window panes with thin streaks of white. The heater groans in the corner, the weak warmth unable to compete with the sharp winter chill seeping through the walls.

Seulgi stands in front of the whiteboard, her marker gliding across its surface in smooth, deliberate strokes. The words Evolutionary Strategies are written in clean, confident lettering, underlined twice with a sharp flick of her wrist. She’s wearing a burgundy fitted dress today, cinched perfectly at the waist to show off her shape. The short hem sits daringly high on her thighs, her legs bare and smooth beneath the fluorescent lights. Her lace-up black heels climb elegantly up to her knees, the ribbons hugging her skin like intricate vines. Combined with the soft, sheer sleeves of her dress and her perfectly straightened hair, Seulgi looks like something out of place in the winter-drab classroom. More like a model in a magazine than a teacher lecturing on biology.

She caps the marker with a soft snap, turning back to face the room. Her gaze sweeps over the students, who sit slumped at their desks. Most look half-asleep, their notebooks open but empty. The back row remain sprawled casually in their seats, arms folded, their books closed like accessories instead of tools for learning.

“For the next part of today’s class,"

She begins, leaning back lightly against the edge of her desk.

“I want you to work individually.”

She pauses, letting the faint murmur of discontent die before continuing.

“Turn to page 67 in your textbooks."

Seulgi crosses her arms loosely over her chest. The action draws subtle attention to the curve of her waist, though she doesn’t seem to notice. Or care.

“I want you to summarize three key strategies that species use to survive: mimicry, camouflage, and dominance.”

The faint groans of protest begin to rise, but Seulgi taps the cap of the marker against the edge of the desk. An unspoken signal to get moving.

“You have fifteen minutes. Use your time wisely.”

As pages start flipping and pens begin scratching across notebooks, Seulgi pushes herself off the desk and begins walking between the rows. Her heels click faintly against the floor with each step, the sound soft yet deliberate. Her gaze moves over the students, her expression calm but observant as she scans their work. Most of them avoid her eyes, their focus on their textbooks, but the back row is different.

The five boys haven’t opened their books.

Seulgi stops behind Seungmin’s desk first. His posture is as lazy as ever, arms folded tightly over his chest as he stares blankly at the textbook he hasn’t touched.

“Seungmin."

She says quietly, leaning just slightly over his shoulder.

“You’re not even pretending to work today.”

Her voice is light, teasing almost, but the proximity of her presence makes him shift slightly in his seat. Her hand grazes the back of his chair as she steps closer, her fingers brushing the cool metal.

“I’d start writing. Unless you want to stay behind after class.”

Seungmin clears his throat faintly, finally picking up his pen as she steps away.

Next, Seulgi moves toward Jaehyun’s desk. He’s leaning back casually in his chair, arms draped loosely over the backrest, his expression blank but his eyes sharp as they flick toward her. His textbook is open, but the pages are untouched.

Seulgi pauses beside him, her heels coming to a quiet stop.

“You look very focused, Jaehyun."

She says, her tone neutral but edged with faint amusement.

Without waiting for a response, she leans over slightly to glance at his desk, one hand resting lightly on the edge for balance. Her posture is calm, unbothered. But her proximity doesn’t go unnoticed.

Her hand shifts, and for the briefest second, her fingertips brush against Jaehyun’s shoulder as she straightens. The touch is featherlight, gone almost as soon as it happens, but Jaehyun freezes. His lazy slouch interrupted as he tenses faintly.

“Keep it up."

Seulgi murmurs softly, as though offering praise.

Jaehyun doesn’t say anything. His eyes linger on the hem of her dress for half a second before darting back to his desk, his hand moving to his pen as though trying to regain his focus.

Seulgi’s heels click softly as she walks away.

Minho is next. He’s slouched deep in his seat, his long legs stretched lazily under the desk. His pen twirls between his fingers, though he hasn’t written a word.

Seulgi stops beside him, tilting her head faintly. “Is that worksheet just for decoration, Minho?”

Minho looks up, his gaze flicking lazily to her.

“I’m still thinking."

He mutters, though the faint grin on his lips suggests otherwise.

Seulgi raises an eyebrow, leaning slightly forward so her fingers rest on the edge of his desk. Her hair falls softly over her shoulder, close enough for Minho to notice the faint scent of her perfume. Light, clean, and distinctly feminine.

“Well, don’t take too long. Time’s running out.”

Her voice is calm, but as she straightens, she lets her gaze linger for just a moment. Her expression unreadable, her posture poised.

Minho stares back, his casual grin faltering just slightly as his hand fumbles with the pen.

The sharp ring of the bell cuts through the quiet. Students jerk upright, grabbing their books and bags with hurried movements.

“Finish what you didn’t complete at home."

Seulgi calls as they begin filing out.

“I’ll be collecting it next time.”

The back row lingers as always. Jaehyun is the last to stand, slinging his bag over his shoulder as he moves toward the door. His gaze flicks toward the desk where Seulgi still sits, though he says nothing as he walks past.

When the room finally empties, the faintest smile is tugging at her lips as she leans back on her hands. She tilts her head back slightly, staring up at the ceiling as she exhales a slow, measured breath. The tension she’s been holding begins to unravel, piece by piece.

Her gaze lowers toward the rows of empty desks, lingering on the seats at the back of the room. Jaehyun. Minho. Jiho. Hyunwoo. Seungmin. Their presence lingers even now, like shadows etched into the fabric of the space. She can still feel the weight of their eyes on her. The stolen glances, the way they’d shifted under her touch.

What are you doing?

The question rises again, unbidden and sharp, but Seulgi shoves it down. She straightens her posture, sliding off the desk slowly. Her heels hit the floor with a soft click, grounding her. The sound feels louder now in the empty room, almost deafening.

She paces toward the whiteboard and begins wiping it clean, her movements slow and methodical. The words she wrote earlier: Mimicry, Camouflage, Dominance, disappear under her hand, as though erasing the evidence of the hour that just passed. And yet, she can’t erase the way her heart still beats just a little too fast.

Seulgi pauses midway through cleaning the board, her hand resting loosely against the marker tray. Her reflection stares back at her faintly from the glass window of the board. Unruffled, poised, perfectly composed. But behind the carefully crafted exterior, there’s something else.

A spark of something dangerous.

Seulgi swallows hard, her fingers tightening faintly around the eraser. She’s not stupid. She knows exactly what she’s doing. Walking that invisible line, teasing just enough to make them look. To make them react. She feels it every time she leans too close, every time her fingers brush against a desk or a shoulder. The thrill hums beneath her skin like a current she can’t shut off.

It isn’t about the boys. It never was.

It’s about the power.

That quiet, intoxicating control she has over the room. Over them.

But what scares her most is how much she enjoys it.

Seulgi turns away from the board and walks toward the window, the tall glass panes fogged faintly at the edges from the cold outside. Her heels echo softly across the floor, every step precise and deliberate. She stops in front of the window, her arms crossing loosely over her chest as she gazes out at the snow-covered courtyard below.

Her reflection stares back at her, sharper now in the cold light. The burgundy dress clings to her figure, the rich fabric catching the dull glow from the overcast sky. The ribbons of her lace-up heels crisscross like ink against her bare skin, accentuating every curve of her calves.

For a brief moment, she wonders what she looks like through their eyes.

Is she still their teacher? The composed, untouchable figure standing at the front of the room? Or is she something else entirely?

Her lips press into a thin line, her breath fogging faintly against the glass.

Why does it feel so good to be seen?

Seulgi doesn’t have an answer. All she knows is that it’s a feeling she can’t shake. The same feeling that leaves her lingering in the empty classroom long after the bell has rung.

She raises a hand absently, brushing her hair back over her shoulder as she leans her forehead lightly against the cold window.

After a moment, Seulgi turns back toward the room. Her gaze drifts toward the back row of desks, where Jaehyun had been sitting just minutes earlier. The desk is empty now, the chair pushed back slightly as though he’d left in a hurry.

She steps towards it slowly, the sound of her heels muffled against the tiled floor. She doesn’t know why she’s walking there. She tells herself she’s simply tidying up, ensuring everything is in its place.

But when she stops in front of Jaehyun’s desk, she hesitates.

Her fingertips trail faintly along the edge of the desk as though testing something invisible.

A sharp knock at the door startles her, and Seulgi pulls her hand back quickly, her heart leaping in her chest. The door creaks open, and one of her colleagues, Mr. Kim from the science department, peeks inside.

“Seulgi-ssi? You’re still here?”

She clears her throat softly, forcing a calm smile onto her face as she turns to face him.

“Just wrapping up."

Mr. Kim nods, glancing once at the empty desks before pulling the door fully open.

“Don’t stay too long. It’s freezing out there.”

“I won’t."

As the door closes again, sealing her back into the empty room, Seulgi exhales. The faint smile fades from her lips as she adjusts the hem of her dress absentmindedly, smoothing it down before turning back toward the front of the room.

She gathers her books and her bag, her movements mechanical as she stacks everything neatly on the desk. But as she prepares to leave, she pauses, glancing once more at the back row of seats.

The thrill still lingers under her skin, warm and unsettling. Seulgi shakes her head faintly, forcing herself to move toward the door.

It’s nothing, she tells herself. Just a game.

But as she steps out into the empty hallway, the echo of her heels against the floor sounds louder than before, as though the classroom hasn’t let her go just yet.

The bell rings, loud and sharp, breaking through the tension that has been lingering in the air for the past hour.

Seulgi sets down her marker and steps back from the whiteboard, brushing faint dust from her yellow plaid blazer. Her skirt, just short enough to skim her thighs, shifts as she walks toward her desk. She doesn’t miss the way the back row lingers. How Jaehyun leans back in his chair lazily, his sharp eyes flicking up from his notebook to follow her movements. How Minho mutters something under his breath to Jiho, earning a faint smirk.

She can feel it. The way their gazes have changed. It’s heavier now. Deliberate. Not the usual distracted glances or harmless stares.

It makes the room feel smaller somehow, the air more stifling.

“Make sure to finish your notes."

Seulgi says, her voice even but faintly clipped as she gathers her papers.

"We’ll review them tomorrow.”

Chairs scrape against the floor as students rise and shuffle toward the door, but the back row takes their time. Jaehyun is the last to move, pushing his chair back slowly, his gaze lingering just a moment too long as he slings his bag over his shoulder.

“See you next time, Miss Kang."

Seulgi pretends not to notice the flicker of amusement in his voice, the faint smile that doesn’t quite reach his eyes. She watches as the five of them finally saunter out of the room, their voices low as they talk amongst themselves.

She exhales softly once the door clicks shut, the tension dissolving into the quiet. But the feeling doesn’t leave her.

What’s gotten into them?

The five of them crowd into an empty corner near the vending machines during the break, their voices low but animated.

“That outfit though."

Jiho mutters with a grin, shaking his head as he cracks open a can of soda.

“See through? She knows what she’s doing.”

“It’s not just the clothes."

Minho replies, leaning against the wall with his arms crossed.

“She’s been teasing us for weeks. You think she doesn’t notice the way we look at her?”

Jaehyun tilts his head, his sharp gaze narrowing thoughtfully.

“Maybe she does. Or maybe she’s just playing around, seeing how far she can push us.”

Hyunwoo finally speaks up, his voice quiet but firm.

"She doesn’t take us seriously. We’re just kids to her.”

The group falls silent for a beat, the words settling uncomfortably.

Jiho scoffs, kicking lightly at the base of the vending machine.

"Well, she’s wrong. We’re not kids.”

“We should let her know that."

Jaehyun says evenly, pushing off the wall with a faint smirk.

“If she’s going to tease us, maybe it’s time we tease her back.”

Seungmin raises an eyebrow.

“And how exactly are we going to do that?”

Jaehyun shrugs, his expression unreadable. “You’ll see. Let’s see how she handles it when the roles are reversed.”

The next class is about to start, and the hallway is a flurry of movement. Students hurrying to their lockers, friends laughing as they weave through the crowd. The noise is chaotic, echoing off the linoleum floors and concrete walls.

Seulgi steps out of the staff room, clutching her binder against her chest as she navigates the crowd. Her heels click softly against the tile, her yellow plaid skirt and blazer standing out like a burst of color against the sea of navy uniforms. Beneath the blazer, her sheer black top hints at the faint curve of her chest, the pattern subtle yet noticeable when it catches the light.

She walks with her usual confidence, though the events of the last class still cling to her mind.

They’re acting differently.

As Seulgi rounds the corner, she almost collides with someone.

“Careful, Miss Kang.”

Jaehyun’s voice cuts through the hallway noise. He’s standing just ahead with the rest of the boys. Minho leaning casually against the lockers, Jiho with his hands shoved into his pockets, Hyunwoo and Seungmin flanking Jaehyun on either side.

The five of them seem to take up more space than they should, their postures loose but deliberate, their gazes fixed on her in a way that makes Seulgi pause.

“Excuse me."

She says smoothly, stepping aside to move past them.

But Jaehyun shifts slightly, his shoulder brushing hers as she passes. It’s subtle, barely enough to notice, but deliberate all the same.

“Heading to the next class?”

Minho asks, his voice low but edged with something faintly mocking.

“Or were you looking for us?”

Seulgi stops mid-step, turning just slightly to face them.

"Watch your tone."

She says quietly, though the calm edge in her voice feels thinner than usual.

Jiho grins.

“Relax, Miss Kang. We’re just saying hello.”

Seulgi narrows her gaze, straightening her posture.

“Then say it properly.”

Hyunwoo chuckles under his breath, earning a glance from Minho, who tilts his head.

“Sure. Hello, Miss Kang. You look... nice today.”

There’s something in the way he says it, casual, almost playful, that makes Seulgi’s breath hitch. For the first time, she feels like they’re seeing her differently. Like they aren’t backing down.

“Thank you."

Her fingers tighten slightly around her binder.

The boys exchange glances, faint smirks playing across their lips. Jaehyun takes one step closer. Not enough to invade her space, but enough to make her notice.

“See you around."

He says softly, his eyes holding hers for a second longer than necessary before he turns to walk away.

One by one, the others follow, their presence lingering even after they disappear into the next corridor.

Seulgi watches them go, her pulse thrumming in her ears. She doesn’t move immediately, standing frozen in the emptying hallway as the noise fades into background static.

What just happened?

They’ve never spoken to her like that before. Never looked at her like that before.

The balance feels like it’s shifting, and for the first time, Seulgi doesn’t know how to respond.

The sound of pens scratching across paper fills the classroom, punctuated by the occasional shuffle of notebooks and the faint hum of the heater. Outside, the snow has slowed, leaving the school grounds dusted in white.

Seulgi sits at her desk at the front of the room, her hands folded neatly over a stack of papers she’s been pretending to review for the past ten minutes. Her gaze drifts occasionally toward the whiteboard, where the topic of today’s biology lesson "Ecosystem Relationships" is written in her neat handwriting.

The students are working on a group assignment, their voices low as they discuss food chains and predator-prey dynamics. Normally, this would be her favorite part of the day, watching her students engage with the material she loves, feeling the quiet satisfaction of a job well done.

But today, her mind is elsewhere.

She can still feel the way they’d looked at her in the hallway earlier. The quiet confidence in their voices, the deliberate way they’d blocked her path without outright disrespecting her. Minho’s low comment, “You look nice today” echoes faintly in her ears, making her shift uncomfortably in her chair.

It’s not the words that unsettled her. It’s the way they’d said them. The way they’d looked at her.

Seulgi exhales softly, her fingers tightening around the edge of the desk. She tells herself it’s nothing. That they’re just boys being boys, testing boundaries the way teenagers always do.

But deep down, she knows it’s more than that.

They’re not backing down anymore.

Seulgi stands, smoothing the hem of her yellow plaid blazer as she walks toward the middle of the room. The students quiet slightly as she approaches, their heads bent over their worksheets.

“How’s it going?"

She asks a pair of girls near the front. Her voice is calm, composed, the perfect balance of authority and approachability.

“Good, we’re almost done.”

Seulgi nods, offering a faint smile before moving to the next group. She forces herself to focus on the present, pushing the earlier encounter to the back of her mind. But no matter how much she tries, the unease lingers, a faint, persistent hum under her skin.

When the bell rings, signaling the end of the period, Seulgi dismisses the class with her usual calm professionalism. But as the students file out, she can’t shake the tension that’s been building since the morning.

Later that afternoon, Seulgi sits across from the vice principal in the quiet staff room. The heater hums faintly in the corner, the warmth doing little to ease the tension in her chest.

“We need someone to oversee detention for the rest of December."

Seulgi blinks, caught off guard.

“Detention?”

“Yes."

He replies, sliding a clipboard toward her.

“Friday afternoons. It won’t take much time, just supervising a few students who need… extra guidance.”

She hesitates for a moment, her mind flickering back to the five boys from earlier. But she quickly shakes the thought away.

“Sure."

Seilgi offers a polite smile as she picks up the pen. “I can handle it.”

“Great."

The vice principal stands up as she signs her name.

“I’ll send you the list of students later today.”

The sun hangs low in the sky, its pale light casting long shadows across the snow-dusted grounds. Seulgi steps outside into the biting winter air, her heels crunching softly against the icy pavement as she makes her way toward the parking lot.

She’s exhausted. More from the weight of her thoughts than the day’s workload. The encounter in the hallway earlier still lingers in her mind, mingling uneasily with the memory of their stares during class.

As she nears her car, the faint sound of laughter catches her attention. She turns instinctively, her eyes drawn toward the football court at the edge of the school grounds.

They’re there.

Jaehyun leans casually against the goalpost, his posture relaxed but deliberate. Minho and Jiho are tossing a football back and forth, their movements lazy and unhurried, while Hyunwoo and Seungmin sit on the bleachers, their voices low as they chat.

Seulgi pauses, her breath catching faintly. She should keep walking, pretend she hasn’t noticed them. But her feet hesitate, her body caught between the familiar thrill of their attention and the quiet unease that has been growing all day.

It’s Jaehyun who notices her first. He straightens slightly, his sharp eyes locking onto hers across the distance. A faint smile tugs at his lips. Not mocking, but knowing.

“Miss Kang!”

Jiho calls, waving her over.

“Taking the long way home?”

Seulgi forces a smile, her fingers tightening around the strap of her bag as she steps closer. “Shouldn’t you all be heading home?”

“Shouldn’t you?”

Minho counters, his tone light but edged with something faintly playful.

She narrows her eyes slightly, though the faint warmth rising in her chest betrays her.

“I could say the same to you.”

Hyunwoo chuckles softly from the bleachers.

“It’s more fun out here.”

“Yeah."

Seungmin adds, leaning forward with his elbows on his knees.

"Don’t tell me you’ve never stayed late to enjoy the quiet.”

Seulgi hesitates, the words catching her off guard.

“That’s not the point.”

Minho tosses the football once more to Jiho before stepping closer, his hands tucked loosely into his pockets.

“Relax, Miss Kang. We’re not causing trouble.”

Jaehyun pushes off the goalpost, his gaze steady as he approaches.

“It’s nice to see you outside the classroom for once."

“Is it?”

Seulgi raises an eyebrow.

Jaehyun nods, his faint smirk deepening.

"You look different out here.”

The words make her breath hitch faintly, though she quickly hides it behind a polite smile.

“I’m the same person, Jaehyun. You’re just imagining things.”

“Maybe."

His tone is unreadable.

The others chuckle softly, their laughter blending into the cold air as Seulgi adjusts her bag and takes a step back.

“You should all head home."

She says firmly, though her voice feels thinner than usual.

“We will. After you.”

Jiho grins at her.

Seulgi doesn’t respond. She turns and walks toward her car, her pulse thrumming under her skin as their voices fade behind her. But as she reaches the driver’s seat, she glances back over her shoulder.

They’re still there, watching her.

And for the first time, Seulgi wonders if she’s the one being teased.

The lunchroom hums with casual chatter and the faint clatter of cutlery against plates. Kang Seulgi sits at a long table near the window, her black off-shoulder dress a striking contrast against the muted winter light streaming in. The fabric hugs her curves just enough to be flattering but not inappropriate, and the gold buttons glint softly under the fluorescent lighting.

She picks at her salad absentmindedly, half-listening to the conversation around her. A few of her colleagues are discussing an upcoming school event, their voices pleasant but not enough to hold her attention. Her mind keeps drifting. To the way the boys had looked at her yesterday. To the way they talked with her, that still echoes faintly in her ears.

It’s not like her to get distracted. But there’s something about the way they’ve started acting lately. More deliberate, more... aware.

Her thoughts are interrupted by a burst of laughter from the hallway just outside the lunchroom. She glances up instinctively, her fork pausing mid-air as the sound grows louder.

And then she sees them.

The five of them walk past the open door in a loose, confident group, their voices carrying easily into the room. Jaehyun is in the lead, his broad shoulders squared and his sharp profile catching the light. Minho walks beside him, gesturing animatedly with his hands, while Jiho trails just behind, grinning at something Hyunwoo has said. Seungmin brings up the rear, his posture relaxed but his eyes sharp as they flick toward the lunchroom for a brief second.

“She’s so hot."

Jiho mutters, loud enough for Seulgi to hear.

“Those legs."

Minho adds, his voice laced with admiration. “Seriously, who wears a dress like that to school?”

Jaehyun chuckles softly.

“Maybe she knows exactly what she’s doing.”

The words send a jolt through Seulgi’s chest. Her first instinct is to brush it off as harmless banter, the kind of talk teenage boys engage in without thinking. But something about their tone, the quiet confidence, the deliberate volume, makes her pause.

She sets her fork down carefully, her gaze following them as they disappear around the corner.

Her thoughts twist uncomfortably. For the first time, she doesn’t just think about their words or their looks. She thinks about them.

The way Jaehyun’s shoulders fill out his uniform blazer. The faint definition of Minho’s forearms when he rolls up his sleeves. How Hyunwoo’s quiet confidence seems to anchor the group, or the way Jiho’s smirk carries just enough charm to disarm anyone. Even Seungmin, the quietest of them, moves with an ease that feels deliberate.

They’re taller than her. All of them. Broader, stronger. It’s not something she’s ever let herself notice before.

But now that she’s thinking about it, she can’t stop.

It happens later that afternoon, just as the final bell rings. Seulgi is walking toward the staff room when she catches the faint scent of cigarette smoke drifting through the open hallway window.

She pauses, her brow furrowing as she follows the smell toward the back of the building. The small, secluded courtyard is barely used during school hours, and it doesn’t take long for her to spot the culprits.

There they are, huddled in a loose circle near the fence. Jiho is holding a cigarette between his fingers, the smoke curling lazily into the cold air, while Minho leans against the fence with his hands in his pockets.

Seulgi feels a surge of irritation, though she isn’t sure if it’s because of their blatant disregard for school rules or the faint thrill she feels at catching them in the act.

“Seriously?"

She steps into the courtyard. Her voice cuts through the air like a whip, and all five heads snap toward her.

Minho straightens immediately, his hand going to the back of his neck as he glances at Jaehyun, who doesn’t move. Jiho, ever the bold one, smirks faintly and stubs out the cigarette against the ground.

“Miss Kang."

Jaehyun says smoothly, his tone calm but edged with faint amusement.

"Didn’t see you there.”

“Clearly."

She replies, crossing her arms. Her gaze sweeps over them, her voice firm.

“Smoking on school grounds is against the rules. You know that.”

Hyunwoo shrugs, his posture unbothered.

“It’s just one cigarette.”

“One is enough."

She snaps, her frustration flaring.

“Detention. Three weeks. Every Friday after school.”

Jiho whistles low under his breath, but Minho elbows him sharply before he can say anything.

“Understood."

Jaehyun's tone is unreadable.

“Good."

Seulgi turns on her heel. But as she walks away, she can feel their eyes on her back, heavy and deliberate. Although, it's not really her back they are staring at, is it? She can almost sense how they're lifting the hem of her dress in their heads. How they're imagining what she's hiding underneath.

The first detention session begins later that afternoon. The classroom is cold and quiet, the fluorescent lights casting a harsh glow over the rows of desks. Seulgi sits at the teacher’s desk, her legs crossed as she reviews papers, doing her best to ignore the faint tension that hums in the air.

There are a few other students in the room. Three girls from another class and two boys from the football team. They’re seated at the front, diligently working on their assignments.

But it’s the boys in the back that have her attention.

Jaehyun, Minho, Jiho, Hyunwoo, and Seungmin are spread out across the last two rows, their postures relaxed but their gazes anything but. Seulgi doesn’t look at them directly, but she can feel it. Their eyes. Their focus. It isn’t like before. They aren’t just looking.

They’re observing.

Testing.

She shifts slightly in her seat, adjusting the hem of her dress as she pretends to focus on her work. But every movement feels amplified under their scrutiny, every click of her pen or shuffle of paper resonating louder than it should.

When the clock finally ticks past five, Seulgi stands and dismisses the group with a curt nod. The other students leave quickly, eager to escape the monotony of detention.

But the five of them take their time.

Jaehyun is the last to leave, his hand lingering on the doorframe as he turns back to glance at her. “See you next week, Miss Kang."

He says softly, his voice low enough that it feels like a promise.

Seulgi exhales slowly once the door clicks shut. She sinks into her chair, her fingers gripping the edge of the desk as she stares at the empty room.

For the first time, doubt creeps in.

You’ve teased them too much.

She knows it now. Knows that this isn’t just harmless fun anymore. They’ve crossed some invisible line, and she can feel the boundary between them beginning to blur.

And the scariest part is that she doesn’t know if she wants to stop it.

The bottle of red wine sits open on the coffee table, its deep, ruby liquid glinting faintly under the warm light of the living room. Seulgi is curled up on her couch, her legs tucked beneath her as she stares at the glass in her hand. The rich scent of the wine mingles with the faint chill in the air, but it does little to ease the knot in her chest.

She takes a slow sip, the warmth spreading down her throat and settling heavily in her stomach. Normally, this is her favorite way to unwind. A quiet evening at home, soft music playing in the background, a glass of something indulgent in her hand.

But tonight, the quiet feels oppressive. Her mind won’t stop racing.

The events of the day replay over and over again. Their voices in the hallway, the way they’d looked at her during detention, Jaehyun’s soft “See you next week” that had lingered in the air like smoke.

Seulgi presses her lips together, swirling the wine in her glass as she leans back against the cushions. For weeks now, she’d told herself it was harmless. The teasing, the outfits, the occasional comment that danced dangerously close to the line. It was all just a game.

But now, sitting alone in the dim light of her apartment, she knows it’s more than that.

They’ve crossed the line.

And so has she.

Seulgi closes her eyes, tilting her head back against the couch as the memories come rushing in.

The first time she’d worn something a little too tight to class, just to see if they’d notice. The way Jaehyun’s gaze had lingered a second too long, or how Jiho had muttered something under his breath that made Minho smirk.

The deliberate way she’d dropped her pen that day, bending over just enough to feel their eyes on her. The thrill that had sparked under her skin, the quiet satisfaction of knowing she could command their attention without saying a word.

She’d told herself it was nothing. That she was in control.

But today, in that cold detention room, she hadn’t felt in control at all.

What happens now?

Seulgi takes another sip of wine, her thoughts spiraling as she stares into the dark liquid. She knows she could stop this, could pull back, enforce stricter boundaries, shut down any future interactions before they cross into dangerous territory.

But deep down, she wonders if it’s already too late.

And the scariest part is the question she can’t bring herself to answer: What if I don’t want to stop?

Her fingers tighten around the stem of the glass as she thinks about them. How confident they’ve become, how deliberate their words and actions feel now.

How far would they take it if I let them?

The thought sends a shiver down her spine, and she can’t tell if it’s fear or something else entirely.

Meanwhile, in a house on the other side of town, Jiho lounges on his bed, his laptop balanced precariously on his knees. The glow of the screen casts sharp shadows across his face, highlighting the faint smirk tugging at his lips.

His cursor his hovering over the actress's picture. His favorite. She's already appeared in so many videos, he'd never be able to watch all of them.

As he unbuttons his pants, he clicks on her name underneath the picture.

Kamimoto Kotone

Scrolling through her videos, Jiho takes out his cock. He doesn't have anything specific in mind. And yet, the cursor comes to a hold over a video he has watched a couple of times already. The thumbnail alone makes him rock hard. He clicks on it, closes the annoying pop up ads, skips forward until he can be sure there is on annoying build up and then leans back.

Perfect timing.

Kotone is kneeling on the floor, her black top and short skirt from the thumbnail already missing. She's holding a cock in each hand, stroking them, while someone else is fucking her face.

The theme is obvious. School. Teacher. Students. Gangbang.

Once the guy inside her mouth can't hold it in anymore, he pulls out and cums all over Kotone's face. Her glasses are covered in his cum, some of it hit her cheeks and mouth as well. She makes a show out of licking her lips, while staring into the camera.

With his left hand, Jiho skips ahead a little.

Now Kotone is getting fucked by someone in a locker room. She's bent over the bench while one guy fucks her from behind and another shoves his cock into her mouth. Her muffled moans echo through the room as the guys pick up the pace. Her hair is all messed up, spit is falling out of her mouth. Kotone ruins the bench underneath her when the guy inside her pussy makes her squirt. Her juices ruin the wooden bench and the floor underneath it, leaving her a shaking mess. It doesn't stop her two students from using her. Soon, both of them groan and Kotone freezes as they both thrust as deep into her as possible and unload at the same time.

Jiho skips ahead again. Already feeling his orgasm building. Seeing Kotone act like a slutty teacher is turning him on more than ever before.

Now, Kotone gets fucked by two guys at once. They're bouncing her on their cocks. One in her ass, one in her pussy. Her cries for more echo through the classroom. Around them are standing even more students. All of them naked from the waist down, ready to have a go at her as well.

After the two guys cream pie both of her holes, another guy lies on the floor, making Kotone straddle and ride him. Three other guys step forward, shoving their cocks into her face. Kotone does her best to give them all equal attention, while bouncing on her other student's dick.

Jiho groans as his orgasm is only seconds away.

He watches how the scene is coming to and end. The ten guys that were using Kotone are now standing in a circle around her. She does her best to make them all cum. It doesn't take long. Soon, Kotone gets hit with one load after another. Cum starts to coat her whole face. Glasses, forehead, hair, cheeks, nose, lips, her open mouth. She takes it all with pride.

Jiho leans back against the headboard, exhausted. His dumb smirk widening faintly as he imagines another face in place of the Kotone's.

Miss Kang.

The thought sends a flicker of heat through him, and he can’t help but replay the events of the day in his still numb mind. The way she’d caught them smoking, her voice sharp but faltering slightly at the edges. The faint flush in her cheeks during detention, the way her eyes had darted toward them even when she tried to pretend she wasn’t looking.

“She likes it."

He mutters under his breath, his voice low and amused.

"She’s been teasing us for weeks. No way she’s not into it.”

He watches the video transitioning to the next scene. Kotone is teaching a class and everything seems normal. But there's that one student in the back. A remote control in his hand. Kotone starts to react to what probably is a vibrator. Her voice becomes higher as she talks. She rubs her thighs together right in front of the class. Moans start to escape her mouth.

A knock at the door startles him, and Jiho quickly slams the laptop shut and covers himself with his sheets, his heart pounding as his younger brother pokes his head inside.

“Dinner’s ready."

“Yeah, I’ll be down in a minute."

As the door closes, Jiho exhales slowly, running a hand through his hair. The movie might have been a fantasy, but the thought of Miss Kang feels far more real.

The vibrator at the end gave him and idea. An idea, none of the boys will hate. An idea which will make Miss Kang act like a Japanese porn star.

Seulgi sets her empty glass on the table, the wine leaving a faint warmth in her cheeks. She leans forward, resting her elbows on her knees as she stares at the darkened window.

She knows they won’t stop. Not now.

And the truth is, she doesn’t want them to.

But as the weight of her actions settles heavily on her shoulders, another thought begins to take shape, a quiet, nagging fear that whispers in the back of her mind.

What happens when they want more than just a game?

The Winter Festival is in full swing, the usual hum of the school replaced by bursts of laughter, applause from the gym, and the faint buzz of conversation that drifts through the hallways. Parents stroll through the classrooms, admiring student projects, while clusters of students hang out near the vending machines and auditorium.

Seulgi moves quietly through the chaos, her black off-shoulder dress a striking silhouette against the pale winter light streaming through the windows. She had thrown it on in a rush that morning, her mind still hazy from the wine she’d indulged in the night before.

Now, as she glances at her reflection in the glass display case by the art room, she feels a pang of unease. The dress had seemed appropriate yesterday. Daring but still professional. But today, with the same outfit, she feels like an unspoken secret is written all over her.

They’re going to notice.

She takes a steadying breath, her heels clicking softly against the floor as she makes her way toward the science wing.

Near the far end of the hallway, where the crowd thins, leaving only the faint echo of distant voices, Seulgi pauses just outside an empty classroom, drawn by the familiar sound of low laughter and murmured conversation.

Inside, the boys’ voices are clear enough to stop her in her tracks.

“So, we’re really doing this?”

Jiho asks, his tone laced with a mix of amusement and anticipation.

“Of course we are."

Minho replies, leaning against a desk.

“You’ve seen the way she looks at us. She’s practically begging for it.”

Hyunwoo chuckles softly.

“Think she’d actually let us?”

“She will. It’s just a matter of time.”

Seulgi feels her breath catch, her heart thudding heavily in her chest. She shouldn’t be listening, she knows that. But her feet stay rooted to the floor as their words continue.

“What about the stuff we talked about?”

Jiho asks, his voice lowering slightly.

“We can use the pins from my place.”

Minho says casually.

“Already took two yesterday. And that thing you asked for, Jiho, it should arrive by tomorrow.”

“Perfect. Anything else?”

Jaehyun asks, a smile on his face.

“Working on it."

Jiho adds with a smirk in his voice.

“Thought we’d keep it simple at first. She’s got to ease into it, right?”

"Right."

Minho agrees.

"This won't be a one time thing."

Laughter ripples through the room, quiet and restrained but heavy with meaning.

Seulgi’s cheeks flush, a wave of heat rushing to her face as she realizes exactly what they’re talking about. Her mind races, a chaotic mix of indignation, disbelief, and something darker, something she refuses to name.

She should step in, say something, confront them. But her body betrays her, frozen in place as their words continue to echo in her ears.

The hallway near the vending machines is quieter now, the distant hum of the festival fading into the background. Seulgi stands in front of the machine, her arms wrapped around herself as she debates whether to grab a drink.

Despite the heat inside the building, she feels cold.

It’s not just the winter air, it’s mainly something else entirely. The weight of their conversation lingers in her mind, the deliberate confidence in their voices, the casual way they’d spoken about her as though their plans were already set in motion.

Her fingers tighten slightly around her arms, her body tense as she tries to shake off the feeling. But the sound of footsteps makes her pause.

They’re here.

Jaehyun is the first to appear, his blazer unbuttoned, his hands tucked casually into his pockets. Minho and Jiho follow close behind, their postures loose and unbothered, while Hyunwoo and Seungmin linger at the back, their quiet presence filling the space with an unspoken tension.

“Miss Kang."

Jaehyun says, his voice smooth as he stops a few steps away.

She forces a smile, her arms still wrapped around herself as she replies.

“Enjoying the festival?”

“Not really our thing."

Minho says with a faint smirk.

“But you seem to be having fun.”

“You look... comfortable."

Jiho adds, his gaze flicking briefly to her dress.

“Same outfit as yesterday?”

The comment lands harder than she expects, a faint flush creeping up her neck as she straightens her posture.

“I was in a rush this morning. Not that it’s any of your concern.”

“Looks good."

Jaehyun says, his tone low but clear.

“Better the second time.”

The words send a faint shiver down her spine, though she quickly hides it behind a calm expression.

“You seem cold."

Hyunwoo says suddenly, his voice quiet but firm.

Before she can respond, Minho steps forward, pulling off his blazer in one smooth motion. He drapes it over her shoulders, his hands brushing lightly against her bare skin as he adjusts the fabric.

The touch is slow. Too slow. His fingers linger just long enough to send a ripple of warmth through her body, his presence behind her impossibly close.

“There."

He says softly, his voice barely above a whisper.

“Better?”

Seulgi swallows hard, her breath catching as she steps away, her fingers brushing against the lapels of the blazer.

“Thank you."

She says stiffly, her voice tight.

Minho steps back, his faint smirk mirrored by the others as they exchange glances. But none of them say anything more.

“See you around, Miss Kang."

Jaehyun's tone is dangerously calm as he turns to leave.

The others follow, their footsteps fading down the hallway until all that’s left is the quiet hum of the vending machine.

Seulgi exhales slowly, her hands tightening around the edges of the blazer. For the first time, she feels like the ground beneath her is slipping.

They’re not just playing anymore.

And deep down, she wonders if she ever had control to begin with.

The biology classroom feels colder than usual. Seulgi stands at the front, her brown silk blouse and matching leather shorts perfectly tailored, but offering little comfort against the quiet chill that has settled over the room.

It’s not just the temperature. It’s them.

For the entire week, Jaehyun, Minho, Jiho, Hyunwoo, and Seungmin have been a shadow of themselves. They’ve sat in the back row as always, their postures relaxed, their expressions unreadable. But the glances, the teasing smirks, the quiet confidence that once left her unsteady - they’re gone.

Seulgi’s voice carries through the room as she explains the day’s lesson on genetic inheritance, but her mind drifts, her focus splintering with every passing moment. She catches herself glancing toward the back row, searching for something, anything, but they don’t even look up.

At first, she’d felt relieved.

The weight of their attention had always been intense, pressing down on her in ways she couldn’t fully explain. She told herself this silence was a blessing, a return to normalcy.

But as the week dragged on, the relief turned into something else.

Now, standing at the front of the room, her hands lightly gripping the edge of her desk, all she can feel is disappointment.

Why aren’t they looking at me?

The thought rises unbidden, and she immediately tries to push it away. But it clings stubbornly to the edges of her mind, a quiet ache that she can’t seem to shake.

Her gaze flicks to Jaehyun for a brief moment. He’s leaning back in his chair, his eyes fixed on his notebook as though she isn’t even there. Minho, sitting beside him, rests his chin on his hand, his expression neutral.

You wanted this, she tells herself, gripping the edge of the desk tighter. You wanted them to stop.

But deep down, she knows it isn’t true.

Her thoughts drift to last week. To the vending machine, to Minho’s quiet comment about her dress and the way he’d draped his blazer over her shoulders.

Her fingers move almost instinctively, brushing lightly against her shoulders,which are covered by the silk, as the memory unfolds in her mind.

He’d stood so close, his hands lingering just a second too long, the warmth of his touch seeping into her skin. It had been fleeting, barely enough to register. And yet, the thought of it now sends a faint shiver through her body, her skin prickling with the memory of his fingers.

Seulgi’s hand drops quickly, her cheeks flushing as she forces herself to focus on the lesson. But her thoughts betray her, spiraling into dangerous territory.

What would it feel like if it wasn’t just him?

The question twists in her mind, unspoken but heavy. Her imagination betrays her, conjuring images of their hands - strong, confident, deliberate - brushing against her skin, leaving trails of heat in their wake.

She shakes her head slightly, trying to dispel the thought, but the faint tingle it leaves behind lingers stubbornly.

The bell rings, snapping her out of her thoughts. Seulgi straightens, her professional mask slipping back into place as she watches the students file out of the room.

“Leave your worksheets on your desks. I’ll collect them after class.”

The chatter fades as the last student leaves, the room falling into a quiet stillness. Seulgi exhales softly, walking between the rows of desks to collect the papers.

She starts with the back row, her eyes flicking briefly to Jaehyun’s neat handwriting as she picks up his worksheet. She lingers for a moment, her fingers brushing against the edge of the desk before moving to the next.

The classroom feels emptier than usual, the silence pressing down on her as she makes her way back to the front. But as she approaches her desk, something catches her eye.

A small box sits neatly on the corner of her desk, its metallic gold wrapping paper shimmering faintly under the fluorescent lights.

Seulgi freezes, her heart skipping a beat as she stares at it. Her fingers hover hesitantly over the ribbon, her pulse quickening as she glances toward the door. The hallway is empty, the faint sound of students laughing and talking in the distance the only sign of life.

Her hands tremble slightly as she unties the bow, the soft whisper of the ribbon echoing in the quiet room. She lifts the lid carefully, her breath catching as she takes in the contents.

Nestled in a bed of tissue paper is a set of black lace lingerie, delicate and intricate, the fabric soft against her fingertips. Beside it, a small, sleek vibrator glints faintly, its design both subtle and unmistakable. But what sends her pulse racing is the folded piece of paper tucked beneath it all.

Her fingers fumble slightly as she unfolds the note, her eyes scanning the words written in neat, confident handwriting:

“I hope you enjoy yourself during detention today.”

Seulgi’s breath hitches, her chest tightening as she rereads the note. Her thoughts spiral in a chaotic mix of disbelief, indignation, and something darker, something primal. Something she shouldn't be feeling.

She knows who left this. She knows.

But the thought of confronting them, of walking into detention later that day with this knowledge, sends a shiver through her body that she can’t ignore.

For a long moment, she just stands there, her hands gripping the edges of the box as the weight of the situation settles over her.

She should feel angry. Outraged. But all she feels is the faint hum of adrenaline coursing through her veins, her body tingling with a nervous energy she can’t shake.

As much as she tries to deny it, the thought of them, their deliberate confidence, their quiet boldness, sends a thrill through her that leaves her breathless.

Seulgi closes the box carefully, her movements deliberate as she ties the ribbon back into place. She picks it up, cradling it against her chest as she steps toward the door.

Her heels click softly against the floor as she walks down the hallway, the weight of the small box a constant reminder of what’s waiting for her later.

How far will they take this?

The question lingers in her mind, heavy and unanswerable, as she disappears into the crowd.

The teacher’s bathroom is quiet, the muffled hum of the school day fading into the background as Seulgi locks the door behind her. The latch clicks into place, the sound sharp and final in the otherwise silent space.

She leans against the door for a moment, her chest rising and falling with steady breaths as she stares at the small gold box in her hands. The wrapping paper is slightly crinkled from where she had gripped it too tightly earlier, but the red bow remains intact, its bright color a stark contrast against the polished white tiles of the bathroom.

Her reflection in the mirror catches her attention, and she steps forward, setting the box on the sink as she studies herself.

The blouse and shorts she’d worn all day fit her perfectly, the soft fabric hugging her curves in a way that feels both natural and deliberate. But now, as she looks at herself under the harsh fluorescent lights, she feels a flicker of doubt.

What are you doing?

Her fingers tighten around the edge of the sink as the question echoes in her mind. For weeks, she’d played this game, pushing boundaries, testing limits, both theirs and her own. She told herself it was harmless, just a bit of fun to break up the monotony of her days.

But it hasn’t felt harmless in a long time.

The note from earlier flashes in her mind:

“I hope you enjoy yourself during detention today.”

The boldness of it, the confidence, had sent a rush of heat through her chest that she couldn’t ignore. They weren’t just playing anymore. They were testing her, pushing her in ways she hadn’t anticipated.

And the scariest part is that she doesn’t want to stop them.

Seulgi’s hands tremble slightly as she opens the box again, her breath catching as the contents are revealed. The black lace lingerie glints softly under the light, its delicate fabric both alluring and intimidating. She brushes her fingers against the lace, the softness of it sending a shiver through her skin.

"This isn’t you."

She thinks, her reflection staring back at her with wide, uncertain eyes.

"You’re their teacher. You’re supposed to be in control."

But control is the last thing she feels right now.

For a long moment, Seulgi just stands there, her thoughts spinning in chaotic circles as she stares at the lingerie. She knows she could leave it in the box, walk into detention as if nothing has changed, and draw a firm line between them.

But another thought creeps in, quieter but no less powerful.

What if you don’t want to draw that line?

Her cheeks flush as the thought takes hold, her fingers curling tightly around the fabric. The memory of Minho’s touch rises unbidden in her mind. The way his hands had lingered on her shoulders, warm and deliberate. She imagines what it would feel like if the others touched her the same way, their hands exploring, testing, leaving trails of heat across her skin.

Her body tingles at the thought, a faint ache settling low in her stomach as she closes her eyes.

When she opens them again, her reflection looks different. Her uncertainty is still there, but beneath it is something else. Something curious, daring, almost reckless.

Slowly, she reaches for the lingerie, her hands steadying as she lifts it out of the box. The delicate lace feels cool against her palms, its intricate design both beautiful and suggestive.

Seulgi hesitates for a moment, glancing towards the locked door as if expecting someone to knock. But the hallway remains silent, the school almost empty save for the few students in detention.

Taking a deep breath, she begins to undress.

The brown blouse is the first to go, the soft fabric sliding over her head and leaving her upper body bare. She folds it carefully, setting it on the counter before she starts to wiggle out of her tight shorts. They fall to the floor in a soft heap, and she steps out of them, her bare legs feeling exposed under the bright lights.

Her plain white panties are the only thing that is covering parts of her body now. Seulgi hooks her fingers into the waistband and slowly pulls them down. Minho's touch suddenly reenters her mind. And as she steps out of her underwear, she can't help but imagine how it must feel like. How good it must feel to have that boys hand travel up her thigh, brushing against her folds...

Seulgi manages to snap out of it. She only has a couple of minutes, before the two hours of detention begin.

She reaches for the vibrator inside the box, but hesitates before picking it up. The sexy lingerie is one thing. But this toy is on a different level. The black lace would already break so many rules, so many boundaries. But the vibrator would make it even worse. If she took it, she'd give up herself. She'd basically offer herself to them. Not just crossing a line in terms of touching, but in terms of something purely sexual. Something that she won't be able to take back as soon as she accepts the complete gift.

Her fingers close around the vibrator. She feels an exciting tingle inside her core as she feels the smooth plastic surface.

Is she really going to give herself to them?

She glances at the note. She rereads it again, the confidence in their words still overpowering her. She can almost see their smug grins, their knowing smiles. Almost as if they always knew it would end like this. Even before she knew herself.

Seulgi sighs as pushes the small object against her folds, the string wrapped around a finger. She isn't completely aroused yet, but there is a certain wetness there. It makes it slightly easier to push the plastic inside of her. Seulgi's breath hitched as she feels it parting her walls. For some reason, she expects it to go off as soon as it's fully inside. But there's nothing. No vibration. Not yet. How would they know anyway?

After making sure the vibrator is in place and the string is there, Seulgi reaches for the black lingerie.

She lifts the lace top over her head, the fabric fitting snugly against her skin. The matching bottoms follow, the high-cut design accentuating the curves of her hips. When she looks at herself in the mirror again, her breath catches.

The lingerie transforms her. The delicate black lace clings to her body in all the right places, the soft fabric highlighting the lines of her figure while leaving just enough to the imagination.

For a moment, she doesn’t recognize herself.

Seulgi quickly puts her blouse and shorts back on, the familiar fabrics a stark contrast to the lingerie hidden beneath. But as she smooths out her blouse and adjusts the collar, she can’t shake the feeling that everything is different now.

She looks at her reflection one last time, her fingers brushing lightly against the edge of the sink. Her heart is racing, her body warm despite the faint chill in the air.

You’ve crossed the line, she thinks, picking up the now-empty box and tucking it into her bag.

But as she steps out of the bathroom and heads toward the detention room, she knows there’s no going back now.

Seulgi didn't dare to look at the five boys as she stepped into the room. The black lace seemed to cling onto her skin. She felt like it got warmer withe every step she took. But when she sat down behind her desk, she realized that they weren't even looking at her. None of them even glanced in her direction. They were all focused on their work.

Just like right now. One whole hour later.

Seulgi can the feel the frustration burning up inside of her. The invisible weight she felt before is now replaced with disappointment.

Did they get cold feet? Surely not. They're way too bold for that.

Did they lose interest? Seulgi shifts uncomfortably in her chair, slowly crossing her legs. Maybe.

She feels the vibrator slightly shift inside of her after her movements. She can't believe this. They are all ignoring her. All five of them.

By now, Seulgi's earlier worries and insecurity have already vanished. She can only feel anticipation and longing. Now that they're not doing it, she is desperate for it.

And she doesn't even notice that she keeps staring at the five of them. Jaehyun seems lost in his work, his pen not coming to a hold even once. Hyunwoo has leaned closer to Minho as if he is explaining something to him.

"No talking, Hyunwoo."

Those are the words that were supposed to leave her lips. But as Seulgi opens her mouth, she feels an unfamiliar vibration rush through her body. The sigh that leaves her lips instead is a mix of pleasure and relief. The vibrator starts to buzz inside of her, just quiet enough so the three girls in the front row can't hear it.

The lowest setting doesn't do much for Seulgi. But the fact that they didn't forget about her already sends a shiver up her spine. She's already aching for their undivided attention.

But when she looks at the five boys again, she realizes that they're still not looking at her. She can't even tell who the person with the remote is. By now, she's already missing the pressure she felt when they looked at her during class. How she could feel their eyes on her ass whenever she wore a tight dress. But now, as she does her best to keep calm, even with a vibrator inside her snatch, they don't even give her a glance.

Seulgi folds her hands on the table, her fingers intertwined as the vibrator takes it up a notch. Still not enough to make her moan, but it definitely relaxes her. She can feel the tension slowly leave her body. Although they're aren't looking at her, she knows they're still interested.

But as detention continues, Seulgi soon faces a new problem. After one of the boys added another level to the vibrator, she's now struggling to hold it in. Her hands, which were lying on the desk mere minutes ago, are now gripping the its edge. She doesn't dare to move otherwise, afraid that the stimulation might cause her to moan.

When the vibrations began, Seulgi started to relax, but as they ramp up, her body tenses again. The vibrator reaches another level and she is now holding onto her dignity. Jolts of pleasure rush through her body, her breath quickening. She's curling her toes, trying to release her arousal in a way that doesn't include moaning or a shaking body. Her breath hitches as she realizes that she's on the highest level. And that it's only a matter of minutes, until this level finishes her off.

Seulgi sits on her chair like a statue, her lips quivering as she does her best to hold it together. Another minute of intense vibrations passes, almost leaving her breathless. She keeps her eyes locked on the last row, still trying to determine which if the boys is holding onto the remote. But she can't see anything, there are no signs at all.

An accidental moan leaves her lips. A wave of panic washes through her. Seulgi couldn't live with herself if the 12 students in front of her heard her moan. She presses her lips together and glances at the clock on the wall. 50 more minutes. Will she be able to fight of the slowly building orgasm for that long?

She can already feel herself shifting in her chair. Her legs are rubbing together, just to have slightly more friction. Seulgi can tell she is close. Too close. Even if she wanted to, she couldn't stop it now. She couldn't walk out into the hall and she wouldn't be able to keep silent in here. While her arousal keeps rising, so does her panic. She is afraid that someone will find out what she's been doing these past weeks. She tries to stop herself from going any further. But as she is at the brink of her orgasm, Seulgi realizes something. And she's realizing it way too late.

She doesn't have control anymore. None at all. She doesn't have control over her own body, not even her emotions. By now, the five boys are in control. They can now do whatever they want. They could make her cum right now. In front of the other students. Or worse, not make her cum. They could leave her hanging. Right on the edge of her orgasm.

Seulgi's legs start to shake a little as the waves of pleasure rush through her. She knows it's only a matter of seconds now.

A gasp escapes Seulgi's lips as the vibrator suddenly falls silent. It's off. It's not doing anything anymore. Through the fog of her pre orgasmic state, Seulgi realizes what just happened. Only a couple of seconds longer and she would've climaxed on the spot. But now this uncontrolled heat rushes through her. This build up orgasm is trying to leave her body, but she is unable to let it go. The vibrator is her gate to pleasure and one of the boys just slammed it shut, right in front of her face.

Anger isn't the right word for it, but Seulgi feels something burn inside of her. Just a couple of seconds longer. It would've been a strong orgasm. Maybe because people would've watched her. But now, they denied her that. And she knows she can't just start playing with herself right here. She wishes she could, but she can't just stick her hand into her shorts and get herself off. But maybe the bathroom...

Just when she wonders if they would let her go or not, she feels the vibrations once more. It's the lowest setting, but it already makes her chest tremble. She can take it easily, but after one more minute, it reaches the next level.

Seulgi is just about to sink back into her chair as Minho suddenly raises his hands.

"Miss Kang, can you help me with this question please?"

He motions towards his worksheet.

Seulgi misses Jaehyun's knowing smile as she tries to stand up. Her legs are weaker than she thought they'd be. And the vibrating object inside of her doesn't make it any easier. With slow, shaky steps, she walks towards the back row.

She feels odd as she comes closer. The five of them must've noticed that she has the vibrator inside of her. It feels like Seulgi has submitted to them. She's basically at their mercy by now.

Standing behind Minho, she glances at all five of them, still trying to figure out who's controlling her. But she can't see a remote, or an open phone. Eventually, she leans down, trying to do her job as a teacher properly.

"What is your answer so far?"

She asks, after having read the question on the worksheet.

Minho shows it to her.

"Do you think I'm missing something? I listed the fish's teeth, predators and colours as part of their natural selection."

"If you..."

Seulgi's breath hitches when she feels a hand on her ass. She doesn't dare stand up straight. She knows it's no use. She can't tell who it is. And if she would look over her shoulder, the hand would already be gone. Instead, she closes her eyes. She can't believe she's letting this happen. She feels one of the boys letting his hand explore her butt.

"Miss Kang?"

Minho asks innocently as if unaware of what's going on.

"Well, if... if you look at the different fish's heads closer..."

She stops as she feels the hand on her ass squeezing one of her cheeks. It's not a gentle squeeze. It's hard and bold. As if the action is telling her, that she has no say about this at all. She doesn't stop it, she just reorganizes her thoughts, before speaking again.

"Some of them are shaped differently. So... So this could be a hint for what?"

As one of the boys keeps squeezing her ass, Seulgi suddenly feels the vibrator reach another level. It's only the second highest, but coupled with the hand on her butt, it feels way better than the first time. She barely notices how she is tightly gripping the edge of Minho's table.

"Is this about their speed?"

Minho still pretends like everything is normal.

"The one with the smaller and longer heads should be faster, right?"

"Ye...Yes. That's correct."

Seulgi lets out a quiet sigh, but Minho must've heard it.

"Thank you, Miss Kang. You're always so helpful."

She responds with another sigh as the vibrator reaches it's final level.

No. Not here.

It's the only thing on her mind. She tries to hold it together. Her thighs are rubbing against each other as she keeps leaning on his desk. The hand on her ass has disappeared by now and she'll never find out who it was.

It lasts only a couple of seconds and the level of the vibrator drops down again. It doesn't turn off, but it's at a lower level.

"Jesus."

Seulgi mumbles under her breath, trying to regain her composure. She wasn't as close to an orgasm, this time, but minute or two longer and she would've cum right there, standing behind them.

Accompanied by the low, steady buzzing inside of her, Seulgi slowly walks back towards her desk. She slides herself back onto the chair, instinctively crossing her legs. But only a moment later, she can feel how the vibrations inside her intensify. This time, it's not a slow build up. Within in a minute, she's reached the highest setting yet again. Seulgi has to bite her own fist to stop herself from moaning. The incoming orgasm feels stronger than the one before. She closes her eyes, knowing that, if she cums now, the whole room will hear her moan.

Instead, her upper body almost falls down onto the desk as the vibrations suddenly stop. She was almost there. So close. And now, her body starts at zero again.

Seulgi's mind start to get a little fuzzy. She looks at the five guys, hoping for only the slightest hint of a reaction. Her breath hitches when she sees Jiho bite his own fist, looking down as if he is concentrating on his work. But he suddenly looks up, shooting a wink at Seulgi's direction.

He saw her struggle. He saw her begging and trying to hide her orgasm at the same time.

A wave of shame hits Seulgi hard and she tries her best to keep her composure. But it isn't easy. Especially now that she knows that they're just acting. They're just teasing her. They know exactly what they're doing to her.

20 minutes. Seulgi had to endure 20 more minutes of this torture, until the bell finally rings for the last time this week. She can't even count how many orgasms the five of them ruined already. But Seulgi isn't seeing clearly anymore. Almost like a dream, she watches the other students pack their things and leave the room one by one. She's almost too far gone to say goodbye. She can almost feel her own mind break. This uncomfortable pleasure that is building up inside of her again and again makes her lose control. Her thighs have started to shake, she keeps on biting one of her pointer fingers, trying to stay quiet.

One of the boys has set the vibrations to a higher level now. Seulgi blushes in shame as she feels a soft trickle of her juices escape her shorts and slowly running down her thighs. She doesn't remember ever being this wet. She never squirted before and her previous partners usually had to use lube to not make the sex uncomfortable. But now, the lace panties feel like someone dropped a bucket of water on them.

Seulgi doesn't even realize that the five boys have stopped working and are just watching her. She's still wearing her glasses, but she can barely see. Her vision blurry as the vibrator reaches the second highest setting.

"Please..."

She manages to whisper, but her voice is too weak.

The guys stand up one by one and walk over to her. She soon feels a hand on her shoulder, then another on her thigh. Seulgi can't even look at them. Embarrassment and arousal clouding her vision. Her head rolls back, when the hand from her shoulder moves down to her chest. A squeeze is enough to make her moan. The hand on her thigh moves towards her core, brushing against her shorts in the process.

"Oh, my god!"

Seulgi moans when she feels even more hands on her. It feels so much better than she thought it would. They drive her towards the edge, towards the point of no return, and just keep her there. Their hands are not enough to free her body from this build up pleasure. If they'd only put on the highest level of the vibrator...

Eventually, someone seems to have mercy with her. Seulgi feels how the vibrations intensify. How her whole body reacts. Their touches and the vibrations send her over the edge in a matter of seconds. She loses her mind as she slowly glides off the chair. Her whole body is quivering and shaking as she reaches the floor. Her mouth is wide open, but not a single sound comes out of it.

When she comes back to her senses, Seulgi realizes the five boys are standing around her in a circle. She looks up at Jaehyun and watches with big eyes as he starts to take of his pants. One last time, some sort of hesitation builds up inside of her. For a moment, she thinks that she can still stop them. That she can still draw line right there.

But when his pants and underwear finally hit the floor, Seulgi has only eyes for one thing. She stares at his cock, which is just centimeters in front of her face.

"Why don't you have a taste, Miss Kang?"

She can hear his mocking tone, but in all honesty, Seulgi doesn't care anymore. The lack of attention from earlier made her crave it now. And there's no way she'd ever let them go.

She leans forward, her lips parting as she feels her students cock slide over her tongue and into her mouth. Seulgi hears the other guys work on their belts and hears their zippers opening as she takes more of Jaehyun's cock. She still can't believe she's doing this. Not with one of her students, but with five of them.

Out of the corner of her eyes, she sees two more dicks pointing at her. She reaches her hands out, her fingers slowly wrapping themselves around Seungmin's and Jiho's cocks. As Seulgi continues to suck on the dick in front of her, she starts to stroke the other guy's cocks, feeling them hardening inside her hands. Jaehyun seems to have already reached full hardness as a groan leaves his lips.

Seulgi makes sure she gets his cock as hard and as wet as possible, before she lets it escape her mouth with a loud pop. She slightly turns, wrapping her lips around Seungmin's cock. Her hand is now on Hyunwoo's dick and Jaehyun's wet one as well. As she starts to stroke them both, she can't help but glance at Hyunwoo. His cock already feels bigger than the other three she already tried. She didn't expect this from him, but the introverted boy has her drooling all over Seungmin's cock. The thought of him fucking her alone makes her wetter than before.

She bobs her head on Seungmin's cock a couple of times, anxious to finally have a taste of Hyunwoo's. When she does switch, she opens her mouth wide, welcoming his length. Her hands wrap around Seungmin and Minho. She closes her eyes, feeling how her mouth gets stretched out as she keeps taking more of him. Seulgi chokes as she tries to take all of it. A dumb smile plays around her lips when she feels him harden even more inside her mouth. She takes her sweet time with Hyunwoo's cock, making sure she coats every inch she can reach with her saliva.

Eventually, she feels an impatient Minho put his hand on the back of her head. She lets him guide her onto his own cock, her hands moving along as well. Her core starts to tingle in excitement as she wraps her fingers around Hyunwoo's drenched cock. Her other hand finds Jiho's cock, making sure she is making him fully hard.

Soon, she gets to him as well. Taking her time, she lets her tongue swirl around his tip whenever she pulls back, before taking most of his cock into her mouth.

"Damn, Miss Kang, I didn't think you'd be this good at sucking cock."

Jaehyun mocks her yet again as he watches her enjoy herself. But with a mouth full of cock, Seulgi can't answer.

Jiho reaches down and starts to undo the buttons of Seulgi's blouse. She feels excitement rush through her, slightly leaning into his touch. Another one of the boys puts his hand on her from the other side. The two of them soon pull the brown silk off her, leaving Seulgi in only the black lace top.

All their eyes are on her and Seulgi feels like she gets drunk on their attention. Shortly after she retreats from Jiho's cock, she wraps her lips around the cock nearest to her. She doesn't care who's it it as long as it's hard for her. Her thighs start quiver once more when the vibrator inside of her starts buzzing again. Two of their hands cup her breasts through the lace.

Seulgi's vision becomes blurry as the pleasure intensifies. She keeps moving around on her knees. One cock here, one cock there. She just takes whoever is closest to her at the moment. Her hands work two more cocks the entire time. She wants to make sure that no one gets left out.

Whenever she reaches Hyunwoo, she makes sure to make herself gag and choke on his cock. She is already in love with its length and girth, her pussy contracting around the vibrator whenever she just thinks of him fucking her.

As she sucks off Minho, Seulgi feels Jaehyun's hand on her ass, squeezing her cheeks through her shorts. The vibrations inside of her intensify as she moans around Minho's cock. Someone is pulling the straps of her bra off her shoulders, revealing her naked chest. As soon as the lace is gone, she feels two hands roaming her tits, playing with her mounds and slightly pinching her nipples.

"I love your cocks so much."

Seulgi can't help but moan when Seungmin forces her off Minho's cock, just so he can pull her head onto his own. She tightly wraps her lips around his length, greedily letting her tongue explore every inch. Seungmin groans in response, amazed by his teacher's cock sucking skills. He can't help but thrust forward, just so he can feel even more of her mouth.

Soon, Seulgi's blowbang has turned into a whole face fuck session. After Seungmin started to deliver a couple of thrusts into her mouth, Jaehyun took a fistful of her hair and forced his cock down her throat. Afterwards, the other boys took turns ruining her face, until Hyunwoo finally took a hold of Seulgi's head.

She's now staring up at his cock, in awe at how big and wet it is. She swallows hard, hoping he will go easy on her. At least at first. The vibrator inside of her basically urges her on to take him into her mouth. Her lips wrap around his shaft once more and her lips glide up and down her his length. Soon, he starts to thrust into her, making Seulgi's eyes roll to the back of her head. He forces her lips apart fully, saliva leaving her mouth in huge strings. They land on her bare tits, thighs and the floor making a mess of her whole body. She tries her best to take it all. To take is whole cock. But she struggles to fit all of it into her mouth. She can't quite reache the base, even while he thrusts into her again and again.

The vibrator keeps buzzing stronger and stronger as Hyunwoo fucks her face harder and harder. Seulgi feels like such a slut right now. Surrounded by five of her students, kneeling half naked on the floor. Their cocks all pointing at her while she's taking a thorough face fucking. She can't even bring herself two take care of two more with her hands. She has to put them on Hyunwoo's thighs to soften the blows a little. But it doesn't feel like it's helping much. Seulgi's jaw starts to hurt as the vibrator reaches the highest level. She shifts around on her knees, her mouth and throat getting stuffed again and again.

Seulgi finally cums for a second time today, almost passing out with Hyunwoo's dick in her mouth. She quivers and shakes on the floor as he slowly lets his cock leave her.

Seulgi gasps and coughs, strings of spit hanging from her chin.

"Let's get you up here."

Jiho and Jaehyun take a hold of Seulgi's shoulders and hips, while Minho pushes her books and her bag off the desk. They lift her up and put her down on the wooden surface. Her legs and her head are dangling off the edges. She feels Jaehyun open her shorts. The boys can already see her waisted lace panties, before her shorts are already gone. Jaehyun pulls them off of her and throws them behind him.

Seulgi can feel the blood rushing into her head and into her pussy. Soon, her panties are gone as well, revealing her glistening wet folds. Seungmin's mouth on Seulgi's tits make her arche her back a little and she stares up and Jiho, who's already standing in front of her face, his cock brushing against her lips. She opens her mouth, a silent invitation for him to use her mouth however he wants.

Seulgi feels someone's cock brush against her folds, making her squirm.

"What about the vibrator?"

Minho's question makes Seulgi's eyes grow wide. Surely they're going to take it out first, right?

"Fuck the vibrator."

Jaehyun says, before pushing his cock into Seulgi's pussy.

Jiho's dick almost falls out of her mouth as Seulgi cries out in pleasure. The vibrator and her student's cock turn her brain into a mess. She soon feels Seungmin's and Minho's mouths on her tits. Her hands hold onto the edge as she tries to keep some sort of sanity.

"Fuck, I didn't expect a teacher to have such a tight pussy."

Jaehyun's words make Seulgi even wetter, while he keeps thrusting into her snatch. She can feel his cock push the vibrator even deeper inside of her. It's position seems to send even stronger vibrations through her.

Seulgi opens her mouth to moan, when not just Jiho, but also Hyunwoo push their cocks past her lips. Suddenly the two of them are filling her mouth and she can barely breathe with so much cock inside of her. All five are using her at the same time. Hyunwoo and Jiho are fucking her upside down face, Seungmin and Minho suck on her tits and Jaehyun takes her pussy like he owns it. She feels his hands holding onto her thighs, while one of the boys on her tits lets a hand wander down her midriff, towards her pussy.

Seulgi can't even moan as the hand reaches her clit, her mouth is too full. She can only gag and choke. But the added sensation of someone rubbing her clit has her mind melting. All the attention, all the pleasure is way too much for Seulgi's body.

The two boys with their cocks in her mouth can basically see how her eyes break, how her mind simply shuts off. Seulgi drowns in a sea of pleasure and she might never make it to the surface. She feels her own spit running out of her mouth and slowly trailing down her face. She gets some of it into her eyes, some into her hair and the rest falls onto the floor beneath her. Her whole head is basically wet with saliva as the two boys keep fucking her face, both their cocks deep inside her mouth and throat.

A few minutes in and Seulgi has lost complete control over her body. She can't do anything against the pleasure they're making her feel. Her clit, her pussy, her tits, her mouth. It's all just too much. She is starting to have orgasms at random intervals, which are not triggered by one thing, but the overall experience. Seungmin and Minho take her hands and guide them towards their cocks. It takes her quite a while, until she's able to give them soft strokes. Her body doesn't listen to her anymore. Seulgi should be worried, but instead she's happy. The feeling of the five boys using, ruining, wrecking her body just surpasses anything she's ever felt before.

But suddenly, Seulgi's pleasure filled brain detects a flash of pain running through her system. One if the boy's mouths on her tits has been replaced with something else. A wooden clothespin. She arches her back off the desk in response, but the pain only seems to amplify her pleasure. Seulgi was never into anything related to pain. But as the second clothespin finds her other boob, she can't help but fall in love with it. Maybe it's just her mess of a brain that makes her think, or rather feel, like this. Either way, Seulgi's body experiences another wave of pleasure rushing through it's system as Seulgi climaxes once more.

"Fuck, Miss Kang. If you do that again, I'm gonna cum in your pussy."

Jaehyun's groaned words barely reach Seulgi's ears. But instead of being scared or worried, Seulgi can feel how her pussy instinctively tightens its walls around his cock.

"Your tits look amazing right now."

Seulgi can't tell who said that and she can't look at herself either. But the pins on her nipples keep increasing her pleasure in some twisted way. Her tits look slightly bigger, although that just might be an elusion.

"Shit, I'm gonna cum too."

Jiho groans as he feels his cock throbbing inside Seulgi's mouth.

But Seulgi is focused on Jaehyun's cock inside her pussy right now. She can feel him thrusting into her even harder, sometimes even hitting the vibrator that keeps on buzzing. His hands hold onto her thighs, his finger's digging into her flesh.

"Fuck!"

He shouts as he finally cums inside Seulgi.

She feels his cum filling her pussy, coating her walls and the vibrator with it. The warmth would make Seulgi smile, if it isn't for the two cocks that are still using her throat. Jaehyun leaves her pussy, but his cock is still hard. Seeing his teacher like this, taking his cum, enables him to go at least one more time. But it's Seungmin's turn now. Seulgi feels his cock rubbing against her folds, before he pushes into her cum filled pussy.

"So fucking wet."

He sighs, unable to keep quiet.

Seulgi feels pride swelling inside of her, but that just might be Jaehyun's cum, which is now getting pushed even deeper inside of her by Seungmin, who is fucking her just like Jaehyun did before him.

"Fuck, cuming!"

Jiho even surprises himself as he suddenly shoots his load down Seulgi's throat. She gags as if cum is filling her lungs. Hyunwoo can't help but groan as her throat massages his cock in the process.

Seulgi can't believe that two of her students just came inside of her. Her mouth and even her pussy. But how much it turns her on is even more worrying. She can almost feel how her body is already begging for more cum.

"Remember this?"

She can barely look up, her head pretty much fixed in place by Hyunwoo's huge cock, which is also blocking her sight. But she can see Jaehyun holding up a red marker. Her red marker. The read marker she used countless times to tease them. She let it drop, she even bit the cap once, or fixed it right between her cleavage after writing.

"Let's use this to keep count."

She watched how Jaehyun opens it and throws away the cap. The teacher inside of her wants to tell him to pick it up, but Hyunwoo's cock inside her only makes her gag a little.

"One cream pie..."

He almost seems to be talking to himself as he reaches for her left thigh. Seungmin stops for a moment, so Jaehyun can draw a line on Seulgi's thigh. He then moves the red marker closer to her face.

"And one throat pie."

Seulgi feels the marker on her throat. Another mark.

She sighs when she feels Hyunwoo's cock leaving her mouth. It feels so empty now, while Seungmin starts fucking her again. After Hyunwoo leaves her sight of view, Jiho appears. He is holding something, but she can't tell what it is. Until he places the ring in her mouth, forcing it wide open, and tying the band at the back of her head.

"Since you won't be doing much talking anyways. Might as well keep your mouth open for our cocks the whole time."

Seulgi can't answer, the big ring in her mouth making it impossible for her to speak. A moment later, she sees Minho stepping in front of her, pushing his hard cock past the ring and her lips. He quickly fills her mouth and once again, Seulgi gets spit roasted by two of her students.

But Jiho was right. Seulgi didn't need to speak while the five boys continued to fuck her. One of them was always inside her mouth and one in her pussy, while the other three made her jerk them off two at the time. Minutes were flying by and Seulgi felt like she had an orgasm during every single minute. When it was finally Hyunwoo's turn to fuck her, Seulgi was seriously worried if his cock was gonna fit. It'd be a shame to not be able to take it. But after some time, he finally managed to fuck her with most of his cock. And it felt way too good. She didn't need to talk to let them know how good. Her boy kept quivering and shaking, her eyes kept rolling to the back of her head, her tight walls kept squeezing their cocks.

"Fuck. This throat feels amazing."

Seulgi feels Seungmin's cock pulsating inside her mouth, right before he orgasms. He pulls out as he does so, most of his cum now running down her face. She feels it hitting her eyes, which are already red, thanks to her own spit.

"I bet her ass feels even better, once we stretch it out a little."

Seulgi is now paying attention. She never had anyone inside her ass before. To now have five boys, just waiting to put it in her butt, has her whole body tingling with worry and excitement.

"Why don't you get your knees, sexy?"

She shivers at their words, but she knows she won't be able to get up without help. Seulgi noticed how they stopped calling her Miss Kang. Not that it makes any difference now anyway.

Minho and Hyunwoo turn her onto her stomach and pull her legs towards her. Seulgi automatically gets on her knees, her head resting on her arms, which are lying on the desk.

She feels at least three hands roaming her ass and squeezing her cheeks. After a short while, someone places his tongue on her puckered whole, giving it slow swipes up and down. It already has her thighs shaking as Seulgi can only imagine how good it must feel like when a cock is inside her ass. When the tongue gets replaced with a bottle of lube, Seulgi shivers in excitement.

"Who wants to go first?"

Seulgi's cheeks turn pink. She's been fucked and used by these five boys for the last half hour and now she gets shy. They treat her like she's some sort of object. Just a set of holes to be used.

"Me."

Seulgi recognizes Jiho's voice. She braces herself as she feels his lubed up cock's tip resting against her hole. As he pushes it in, Seulgi's mind becomes all fuzzy. Her head suddenly feels too heavy. It just feels so good. She never expected it to feel this good. She never dared to try it. And now they are taking her ass like they own it.

"Damn she really is tight. So much better than her pussy."

Jiho's compliment makes Seulgi moan as he pushes deeper, until his hips meet her cheeks.

"That looks amazing."

That's Jaehyun.

"I can't just watch."

She hears him walk towards her head. When he appears, he lifts her head and pushes his cock through the ring into her mouth.

Just like before, Seulgi gets spit roasted again. But this time, they're using her ass, not her pussy. Her body gets rocked back and forth and now she feels a slight pull in her tits, whenever the clothespins brush over the desk's surface. Someone seems to run his hand along her back, taking in the smoothness of her skin. But all of that is insignificant, compared to the cock in her ass. It just makes her head spin with lust and arousal.

Unfortunately, only two of her holes are available in this position. That's why, after Jiho pulls out of her ass, the five of them lie Seulgi on her side, her ass slightly hanging over the edge. Jaehyun keeps fucking her mouth, one of her cheeks pressed against the wooden surface. Seungmin slowly pushes his cock into her ass, waiting until she got used to his cock. Hyunwoo is up next, ready to fuck her pussy again.

Seulgi feels like she loses her mind when the two cocks are buried inside both her holes. She never took two guys at once. Especially not someone as big as Hyunwoo. And now, the two of them seem to completely ruin her lower body as Hyunwoo lifts up one of Seulgi's legs and places her ankle on his shoulder. The screams she needs to let out get muffled by Jaehyun's cock down her throat. She feels Minho and Jiho guiding her hands to their cocks. She wants them to feel good too, she really does, but her body doesn't really work right now. It seems like she can barely do anything else on her own than just breath. She lazily strokes their dicks, while she's getting ruined by three more.

The walls between her pussy and her ass are so tight, the two boys inside both her holes can feel each other's cocks rubbing against each other. It makes them fuck her even faster, which drives Seulgi towards another orgasm. Her tight pussy can barely contract around Hyunwoo's huge cock as she cums.

After that orgasm washes through her, she feels slightly more focused. But she knows it won't last long. She barely notices how Jaehyun and Minho trade places. The later now sliding his cock in and out of her mouth at a steady pace, while Jaehyun relieves her of the clothespins one after the other. The pain that was there for so long is now gone, which makes Seulgi almost miss it. But even her mess of a brain knows that Jaehyun isn't doing this because he wants to stop the pain. He just has more stuff planned.

Moments later, Seulgi's hands are tied behind her back. Her chin is resting on the desk, until both the three boys inside of her pull out. It's the first time in a while that Seulgi isn't getting touched or fucked. She still feels the vibrator inside of her, but that's it. She is now feeling this unsettling emptiness. As if her body has gotten used to being filled completely. She can tell that her ass is now wide open, while her freshly fucked pussy must look like a mess.

Minho makes her lie on her back and pushes his cock inside her pussy once again. Jiho and Hyunwoo help her up and suddenly Seulgi is being carried, Minho's cock still inside of her. As they all step out of the classroom, Seulgi feels how she's slowly coming to her senses. But with every step Minho takes, her pussy slides up and down his cock, which still makes it hard to focus.

How is this gonna end?

Is her first and last proper thought. When they reach the cafeteria, Minho puts her down on one of the large tables. Jaehyun and Jiho disappear. While Seungmin takes the ring out of her mouth, Hyunwoo pushes Minho carefully out of the way.

"Sorry man. I've been holding it in the whole time. But I need to cum. Right now."

His words make Seulgi shiver, instinctively opening her legs a little further.

"A-Are you going to cum in me?"

Her voice sounds hoarse and rough.

All three of them ignore her.

And she's unable to ask another question, once Hyunwoo buries his cock deep inside her snatch. Deeper than before. So deep, he pushes the vibrator even further inside of her. She can feel it hit her cervix. Seulgi can't even worry about how she's going to get it out of her again, when Hyunwoo now properly starts to fuck her. The veins on his cock rub against her walls, which are almost stretched to the limit. She starts moaning immediately, loosing her mind yet again.

The only thing she can feel his Hyunwoo's cock, ruining her pussy as he uses her like a toy. Seungmin turns her head to the side. Kneeling on the bench at the table, he pushes his cock inside of her mouth. Minho focuses on her tits, sucking and licking them with occasional bite.

But soon, Hyunwoo has already reached his breaking point, just like said. He pushes his cock as deep as it can go inside Seulgi, before finally unloading inside of her. Her pussy quickly gets filled to the brim with his cum. She can feels its warmth rushing through her system.

When Jiho and Jaehyun return, Seungmin is having an orgasm as well. He dumps his load inside her mouth, making Seulgi taste it, before she swallows all of it.

Seulgi looks up at Jiho, who is holding a bottle of chocolate sauce. Before she can say anything, he pours all of it onto her body. Her tits, her midriff... All of it gets covered in the brown sauce. Then, Jaehyun puts the whipped cream he brought to her open mouth and fills her with pure sweetness.

And once again, the five boys start to use her body for their own pleasure. Minho and Jaehyun both put their cocks into Seulgi's whipped cream filled mouth. The mix of her body's warmth and the coldness of the cream makes it feel even better now. Jiho takes the whipped cream too and actually puts some of it right onto her folds. He pushes his cock inside her cum filled pussy, taking the whipped cream with him. Hyunwoo and Seungmin both lean over her and begin to lick her whole torso clean.

Seulgi quivers and shakes under all the sensations, which are all happening at the same time. The two boys that are using her mouth make it hard for her to breathe. She feels Hyunwoo's lips circling her tits, while Seungmin licks the chocolate sauce off her toned midriff. And Jiho uses her pussy whoever he wants, going slow or fast, hard or shallow, not caring what Seulgi herself would like.

It is all way too much for her. Once more, her brain turns off. Her body only responds to their will, while they share all of her holes.

"Oh, fuck."

Jaehyun groans after filling Seulgi's pussy with his cum again.

"How is she still so tight after we've cream pied her this often already?"

He adds another mark on her thigh. That's six.

While Minho uses Seulgi's throat, Hyunwoo starts to coat his cock with a thick layer of lube. The whipped cream and the chocolate sauce are completely gone already. But that doesn't make her holes any less addictive. Minho climaxes, shooting his load deep down Seulgi's throat.

Her eyes grow wide, when she feels Hyunwoo's cock against her add.

"Wait, you're too big. Way too big. I can't-"

She lets out a cry when Hyunwoo pushes his tip past the ring of muscles. He immediately makes her brain go numb with pleasure. His cock keeps on stretching out her ass, until he is around halfway inside of her. Seulgi breaths heavily, trying to get accustomed to having her ass filled to this extend. She knows she won't be able to sit for days.

Hyunwoo pulls slowly out of her ass and the pushes back inside. He starts to establish a rhythm, his cock ruining Seulgi's ass. The pleasure makes her go cross-eyed, her tongue slips out of her half open mouth.

The other four guys watch how Hyunwoo makes her fall apart in the middle of the cafeteria. Just hours ago, hundreds of students sat in this room. Now, the six of them are alone.

Eventually, Seungmin can't take it anymore. He took a break earlier, while the other four used Seulgi's body however they liked. But he's been jerking off since then. And seeing Seulgi fall apart right now makes him walk up to her. Just a second too late. He climaxes just when he reaches her face. His cum hits her eyes, her nose, her cheeks and her tongue, making a mess of her already ruined face.

"I can't watch anymore."

Jaehyun walks up to her too. He and Hyunwoo pick Seulgi up and carry her. Jaehyun lines up his cock with her pussy, before he and Hyunwoo slowly pull her down.

"Oh, god! It's so much!"

Seulgi cries, both her ass and her pussy completely full with cock. The two of them make her slide up and down on their cocks.

"I want some of that pussy too."

Jiho walks up to the three of them.

"Wait, I-"

He doesn't wait. Jaehyun and Hyunwoo stop for a second, enabling Jiho to push his cock into Seulgi's already filled pussy. The three of them completely melt her brain. The biggest inside her ass and tow inside her pussy. She's being split open and she can't believe she's still alive. She can't believe her body is able to take all of this. And she can't believe how good this feels.

"Let's fill her up completely."

Seungmin nudges Minho and the two of them climb onto the table Seulgi lied on mere minutes ago. They're all at the perfect hight. As they push their cocks past her lips, Seulgi realizes that all five of them are inside of her. She doesn't know how it's possible. But five or her students are sharing all three of her holes.

At this point, Seulgi doesn't even have orgasms one after another. She feels like she's trapped inside one huge orgasm. Her body can't keep up. She can't calm down. Wave after wave of pure pleasure washes through her body. Her pussy contracts around both cocks inside her. The world around her becomes distant. Her vision gets blurry. Eventually, her brain is unable to comprehend what's going on. The pleasure inside of her completely takes over. She doesn't feel anything else. She can't even moan. It takes too much energy for to be in a constant state of orgasm.

Seulgi realizes she must've past out. She opens her eyes. She's lying on top of a desk, the five boys are standing around her. She can't see the marks on her throat, but the ones on her thigh tell her that at least three of them cream pied her, after she lost her senses. She feels how someone's cum slowly leaks out of her gaping ass. Her whole body feels sore, used, broken.

Barely able to move her head, Seulgi looks around the room.

"No, wait."

Panic rises inside of her. But her voice is barely above a whisper.

"This is...This is...the principal's..."

She can't finish her sentence.

Once again, one of the boys shoves his cock into her mouth. Soon after, she feels the rest of her holes getting stuffed. While they use her again, her juices and sweat and their cum mix and start to stain the principal's desk. The five boys don't care and Seulgi can't stop them. Her eyes are only half open as he manages to glance at the clock, which is hanging on the wall. But she can't read it. It's as if she forgot how to tell time. The cocks inside of her seem to turn her into some brainless slut.

What Seulgi doesn't know is, that two hours have already passed, since the last bell of the day rang. It's 6:30 pm already. And the five boys don't plan on stopping anytime soon.

After using Seulgi as cum dump once again, they move her to the teacher's lounge. They can't help themselves, but have to fuck her right on the new teacher's desk. The new teacher is a cute, young woman, who teaches gym class. Jaehyun uses the jump rope, which was lying on her desk, to tie Seulgi's tits together in a painful way. First the clothespins, now this. Seulgi feels her tits being painfully squeezed by the rope, which will probably leave red marks by the end of the day.

Instead of going back to the classroom, they make Seulgi kneel right in the middle of the hallway afterwards. Just like the beginning, they form a circle around her and use her mouth one at a time. Her whole body is quickly covered in a thick layer of juices, sweat, saliva and cum. Everyone could walk into the school and see her like this. It's not like they're hiding in a classroom or something. But they're making her blow them all right here, in the hallway.

Eventually, the five of them do take Seulgi back to the classroom they had detention in. She can barely think on her own at this point. They have to tell her everything she has to do. After all of them use all her holes once again, they form a circle around her.

Jaehyun frees her of the jump rope. The red marks around her tits are clearly visible. Jiho puts the wooden clothespins back on her nipples, barely making Seulgi flinch. It's almost as if she's immune to anything but pleasure right now. And while she's just kneeling there, hands behind her back, she tries to rub her thighs together, hoping to not fall from this never ending high. Her tongue is hanging out of her mouth as if she is a dog in heat. Jaehyun somehow connects both ends of the jump rope with both clothespins.

"Open wide."

Seulgi obeys, opening her mouth fully. Jaehyun putts the middle of the jump in her mouth an she instinctively closes it again.

"Fuck, she looks like one of these Japanese porn stars right now."

Seulgi has to hold back the urge to lean towards one of the cocks pointing at her. She needs to feel them inside of her again. But the boys have other plans. Jiho and Seungmin snap a couple of pictures. And afterwards all five of them jerk off to the mess they've created.

Seulgi is kneeling on the floor. Naked, clothespins pinching her nipples, which are connected by a rope, that she's holding up with her teeth. Her whole body is covered in her own slick, her sweat, her saliva and the boy's cum. Her hair is a mess too, her eyes are red after getting hit by so much of her own saliva and cum. And even now, cum is leaking out of her ass and pussy. The tally marks on her throat are barely visible anymore. A number between 10 and 15. In contrast to that, her right thigh is completely covered. The number is bigger than the one on her throat.

The pure sight of their ruined Biology teacher eventually makes the boys cum one after another. First, it's Seungmin and Minho. Seungmin is standing on her right, his load hitting her cheek and her nose. Minho, right next to him, hits Seulgi directly in the eye, making it even worse. The other three cum soon after in quick succession. Jiho completely covers her left cheek. Hyunwoo paints her forehead and her hair from behind. And fianlly Jaehyun gives Seulgi's entire face on more layer of cum.

"I'm so fucked."

He groans, still finding it difficult to belive that they pulled all of this off.

"Same time next week?"

Jiho jokes, but he is visibly completely drained as well.

Man, I-"

Minho gets interrupted by the door being thrown open. All of them freeze. Seulgi's brain recovers in an instant and she's almost back to normal in a second. Who wouldn't turn sober, when one of the sudent's, who just used your body for hours without a break, mother stands in the door. Seulgi is very aware of the fact she is complete mess, kneeling inside a crcle of five of her students.

"Miss, Bae..."

--------------

Hi, everyone!

Please enjoy this nice Seulgi story. I apologize for the delay, but writing 19.6k words within a week isn't as easy as it sounds. I'm sure there is even more potential there, maybe even a full second chapter. I won't promise anything, but I did enjoy writing this a lot.

Stay healthy, everyone!
